– An aldehyde has a terminal functional group due to the one hydrogen- Ketone has two alkyl groups so it’s never a terminal group.
An aldehyde is a type of organic compound that contains a terminal functional group called an aldehyde group (-CHO)
An aldehyde is a type of organic compound that contains a terminal functional group called an aldehyde group (-CHO). The aldehyde group consists of a carbonyl group (C=O) attached to a hydrogen atom. This hydrogen atom makes the aldehyde group a terminal group, meaning it is located at the end of a carbon chain in the molecule. This terminal position gives aldehydes distinct chemical properties.
On the other hand, a ketone is also a type of organic compound that contains a carbonyl group (C=O). However, in ketones, the carbonyl group is situated between two alkyl groups (R-C=O-R). Due to this arrangement, ketones do not have a terminal group like aldehydes. The absence of a hydrogen atom attached to the carbonyl carbon prevents ketones from being located at the end of a carbon chain. Instead, ketones are found within the carbon chain or between other functional groups.
In summary, the presence of a terminal functional group (aldehyde group) makes aldehydes different from ketones, which do not possess a terminal group due to the absence of a hydrogen atom attached to the carbonyl carbon.
